Doesn’t it seem odd that Jesus taught a Hebrew prayer in “Our Father”? There’s not a shred of Christianity in it.
Doesn’t seem odd to me, that Jesus, A jew “of the seed of David” according to the flesh, would pray as the Jewish prophets, and teach his disciples to pray to the Jewish God in the same way. There is an unbroken continuity, between Christianity and Judaism. Christianity is Jewish, at the core, it is based upon the revelation God gave to Moses, the prophets, until the fullest revelation came, which is in the person of Jesus the Messiah.
Christianity is Christ, and Christ made Moses, along with the rest of the prophets one and the same as His gospel. Who taught the Hebrews how to pray?
